CROSSING FOR SUSPENDED EI:ECTRIO CONDUCTORS.

SPECIFICATION forming part of Letters Patent No. 659,142. dated October 2, 1900.

Application filed February 2, 1900. Serial No. 3,719. the model.)

To all whom it may concern:

Be it known that I, JOHN FLOYD, a citizen of the United States of America, and a resident of Washington, in the District of Columbia, have invented certain new and useful Improvements in Crossings for Suspended Electric Conductors, of which the following is a specification.

This invention relates to crossings for suspended electric conductors, and more particularly to that class in which the trolley-wheel travels on the top of the conductor.

One object of the present invention is to provide a crossing for suspended electric conductors in which the trolley-wheel travels on the top of the conductor and one that will make a continuous circuit certain.

Another object of this invention is to provide a crossing for suspended electric conductors which will not necessitate the removal of the trolley-wheel and will prevent the liability of the wheel jumping from the wire, the ac,- tion of the crossing being entirely automatic.

Further objects and advantages of the invention will appear in the description and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings which form a part of this specification, Figure 1 is a perspective view of the invention complete. Fig. 2 is aside elevation. Fig. 3 illustrates the trolley-wheel.

Referring by letters to the drawings, A represents one of the main conductors, and B the other. The conductors are connected by my improved crossing, and their free ends are secured in the blocks O, which are held together by an angular plate D and brace-bars E, the object of which will be hereinafter explained. Secured in the apex of the angular plate D by a bolt F are two similarly-curved arms G, pivoted at their centers. These arms are arranged in a reverse position with respect to each other and are held in place by the guides H, secured to the angular plate. One end of each arm is bent up, asshown at I, and provided with a flange J. The other ends are slotted, as shown at K, and are adapted to engage the longitudinal slots L in the blocks. Mounted in the grooves M, which are parallel to the longitudinal slots L, are the sliding rods N, having tongues O, which project down into the bottom of the grooves. These tongues are provided with lugs P, which extend across the longitudinal slots and are adapted to be engaged by the slotted ends of the arms.

In carrying my improved crossing into operation I employ a trolley-pole having two wheels mounted thereon and a notch above the wheels, as clearly shown in the drawings. The larger wheel is intended to travel on the conductor and the smaller one to remain idle until the notch has engaged and passed the flange on the end of the arm, when it raises the arm and closes the crossing by sliding the rod operated by the other end of the arm forward. It then raises the adjacent 'arm and passes under, the arm being lowered by the notch above the wheels.

It will be understood that I reserve to myself the right to vary the form, dimensions, proportions, and necessary parts of this ap paratus and to employ for the construction such materials as I may judge suitable.

I claim 1. In a crossing for suspended electric conductors, an angular plate and brace-rods connecting two blocks, of slots and grooves in the blocks, of sliding rods mounted in the grooves, and adapted to be operated by similar arms, substantially as shown and described.

2. In a crossing for suspended electric conducto rs, an angular plate and brace-rods connecting similar blocks, having slots and grooves therein, of sliding rods mounted in the said grooves and adapted to be operated by similarly-curved arms, substantially as shown and described.

3. In a crossing for suspended electric conductors, an angular plate and brace-rods connecting similar blocks, having slots and grooves therein, of sliding rods mounted in said grooves provided with lugs projecting across the said slots, of similarly-curved arms pivoted at their centers in the apex of the angular plate, the said arms adapted to en"- gage the lugs through the slots and to operate the sliding rods, substantially as shown and described.
